Economist article on climate impacts

This is a solid, if slightly wonky, article from the Economist. If you don't want to get bogged down in "Rossby waves" (not to be confused with Cosby waves) then just remember this:
Episodes of heavy rain and snowfall are now more common around the world than they were 50 years ago, according to the IPCC’s 2007 review of the literature, which is to be expected in a warming world; warmer air can carry more water, and so more can be released when the conditions are right. Reflecting this trend, the Indian monsoon — which in terms of absolute levels of rainfall changed little over the 20th century—has been seeing more of its rainfall in extreme events than it used to. No one of those extreme events can be laid at the door of worldwide climate change; nor can the Russian heatwave. The pattern of increases, though, fits expectations—and those expectations see things getting worse.
So while you can't directly pinpoint one particular event to climate change, you can look at current trends which are cause for serious concern.
